Q

Which respiratory organ is the site of gas exchange?

A

At the end of the terminal bronchioles, there are clusters of alveoli that are the site of gas exchange.

The wall of each alveolus is made of a single-cell layer of squamous epithelium. This thin wall allows for exchange of gases within the capillaries covering the alveoli.

34

A

rapid, deep respirations associated with acidic environment (such as diabetic ketoacidosis)

42
Q

Why would patients with cardiac problems (congestive heart failure) have subsequent respiratory problems?

A

Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs. This fluid reduces normal oxygen movement through the lungs.These two factors combine to cause shortness of breath

Q

why can chronic illness overall leading to muscle weakness effect respiratory function?

A

Muscles that work with inspiration/expiration can be weakened

A
  1. Hypoxia is Inadequate supply of oxygen to the tissues (cells).
  2. It can lead to cellular acidosis, cell death and organ failure.
62

A

Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, usually referring to the delivery of blood to a capillary bed in tissue.

73
Q

What are signs for poor perfusion?

A
  1. Pulse in specfic area is +1
  2. cold skin

74
Q

What does arterial blood gas (ABG) test measure?

What is it used to find out?

A

arterial blood gases (ABG) test measures the following in the blood from an artery:

  1. the acidity (pH)

  3. levels of carbon dioxide

This test is used to find out how well your lungs are able to move oxygen into the blood and remove carbon dioxide from the blood.

75
Q

Which wave does the ECG/EKG begin with?

What does the letter represent?

A

P = atrial depolarization

76
Q

What does the QRS on an ECG/EKG represent?

A

ventricular contraction

77
Q

What does the T phase in an ECG/EKG represent?

A

Ventricular repolarization (relaxation)

78
Q

When a thombus (blood clot) enters circulation what is it called?

A

embolism

79
Q

Why should you not use compression sleeves on a DVT?

A

Compression may dislodge the clot and go to the lungs causing pulmonary embolism.

80
Q

What are the 4 Nursing Interventions to promote proper breathing

A
  1. Deep breathing
  2. Use of incentive spirometry
  3. Pursed-lip breathing
  4. Diaphragmatic breathing
81
Q

The nurse is assessing patients who will receive general anesthesia. The nurse identifies that the patient who is at the greatest risk for complications is the patient with a diagnosis of:

  1. Gastroesophageal reflux disease (GERD)
  2. Hypertension
  3. Hypothyroidism
  4. Emphysema
A

Respiratory problems complicate the administration of inhalation anesthesia.

Emphysema is characterized by the destruction of alveoli, loss of elastic recoil, and narrowing of bronchioles, which result in alveolar hyperinflation and increased airflow resistance.
